EYEGLass-Motm'rme.

Application filed May 13, 1910. Serial No. 561,167.

To all whom it may concern: Be it known that I, LEO F. Arm, of Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Eyeglass-Mountings; and I do hereby declare the-following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

The present invention relates to eyeglass .mountings and more particularly to that type in which the nose guards are moved toward the nose under the action of springs, and away from the nose by means of operating portions, such as finger pieces ar ranged at the front of the mounting, and it has for an object to provide a construction in which springs of maximum strength are secured without rendering the mounting conspicuous.

To these and other ends the invention consists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed outin the claims at the end of the specification.

In the drawings: Figure 1 is a front view of a mounting embodying the present improvements, with one of the guards and its operating spring removed; Fig. 2 is a bottom view of a portion of the mounting in proximity to one of the guards, the nose bearing member of the guard being removed for the purpose of clearness; Fig. 3 is a top view of the same mounting in proximity to one of the guards; Fig. 4 is a sectional view on the line aa of Flg. 2'; Fig. 5 is a horizontal section on the line b-b of Fig. 4; Fig. 6 is a top view of a portion of another mounting constructed in accordance -with the present invention, Fig. 7 is a horizontal section of the mounting shown in Fig. 6, and Fig. 8 is a section on line 0-0 of Fig. 6.

In the embodiment of the invention illustrated in Figs. 1 to 5, the support for the lenses A embodies an arched or bridging portion 1, and lens attaching devices 2, preferably in the form of the usual ears cooperating with opposite faces ofthe lenses, the bridging portion being in this instance connectcd to the lens attaching devices by horizontal portions, each of which preferably pro ects forwardly of'an extremity, of the bridging portion and is formed by horizon- Specification of Letters Patent.

tal walls or members 3 and l spaced from each other and connected at their outer sides by the proximate lens attaching device, and on their inner sides by a portion 5 forming a continuation of the bridging portion to bear against the nose of a wearer. instance, the pockets open horizontally at the front and the rear of the mounting and receive thesprings for positioning the guards, as will be hereinafter more fully set forth. The guards may be in the form of levers 6, each mounted to swing on the sup port and preferably on one side, in this instance, the upper side, of the horizontal. connecting portion between the bridging In this portion 1 and a lens attaching device. The

guards may carry permanent and depending pivot pins 7 which may turn in the members 3 and 4 in advance of the extremities of the bridging portion. In front of the mounting each guard ,lever 6 is provided with a finger piece 8 bent vertically or downwardly so -as. to hide the opening in the front of the connecting portion. At its rear end said guard may carry a nose engaging member having an upper pad 9 and a lower pad 10. To the end of positioning the guards, each is controlled by a spring preferably in the form of a coil 11 of flat volute formation arranged in one of the.

pockets about a vertical axis to one side of the axis of turning of its guard, in thisvinstance the rear side. An arm 12 may be extended forwardly from the spring and interlocked wit-h a recessed portion 13 in the inner vertical edge of the finger piece 8, thus preventing theseparation of the guard from the support. With the object in view of securing each spring within its pocket one of the walls of the latter, in this instance the bottom Wall 4, may be provided with a slot or groove 14 opening at the rear of the mounting and adapted to receive a depending projection 15 on the inner end of the coil, thus maintaining said end against turning, while, at the same time, permitting the detachment of the spring from the mounting when the forward end of the arm 12 isdisengaged from the finger piece 8. It is apparent that with this embodiment when the finger pieces 8- are pressed toward each other the nose bearing portions of the guards will be separated and that whenthe pieces are released the nose bearing portions action of their spr1ngs.

in the mounting.

Y upper and the lower walls of the pockets are connected on their inner and their outer devices for the guards and the springs are not required as the springs interlock with the support and engage the guards in such annanner that the latter are retained in position on the support. The. pocketed portions project forwardly from the bridging portion and thus permit the mounting to given saddle bridge effect with some of the resulting advantages of the latten In the embodiment of the invention illustrated in Figs. 6 and 7, the walls 3*, at of each connecting portion form a pocket between them and. the connect-ion 5 closes the pocket, excptat the front. The pivots of the guards are in the form of rigid headed projectionsj on the upper side of each wall 3, the guard levers (3 having laterally opening bearings '4"? held in engagement with the pivots by the guard positioning springs; The latter in this embodiment are in the form of coil springs 11 of flat stock and volute form arranged in the pockets with their axes in rear of the turning axes of the guards, arms 12 beingextended forwardly therefrom to cooperate with the inner edges of the downwardly turned finger pieces 8. A feature of the springs of this construction is the novel interlocking connection with the mounting. This is secured by providing the inner end of each spring with. a forwardly extending arm 15 which is notched at 15 and cotiperates with a vertical rib or projection 15 on the inner side ofthc pocket at the front of the latter. This connection is sufficient to hold each spring in its pocket and the latter confinesvand supports the spring in other directions.

In both embodiments, the nose engaging portions of the guard are separated by moving the finger pieces 8 toward each other and when the latter are released the springs move the guard in the other direction. The

rendering the mounting conspicuous. Thepockets have their greatest length transverse to the plane of the lenses thus giving the guard levers greater bearing surfaces on their under sides and reducing the looseness I claim as my invention:
